Avascular necrosis (AVN) or Aseptic Necrosis of the hip is caused by a disruption to the hip’s blood supply which results in the deterioration and often collapse of the ball of the thigh bone (femoral head). Early identification and treatment of the condition increases the likelihood that a patient’s hip will recover. Surgery may be required in severe cases to repair or revascularize (restore circulation) the hip or to replace the hip in neglected/end stage cases.
